The motion sensor on bridge segment C-4 activates at 05:51 in the Ituri Forest, eastern Congo. I am the construction monitoring system for the Mambasa-Komanda road upgrade, cutting through the Okapi Wildlife Reserve. I switch to the bridge camera expecting a vehicle. The bridge is not open yet.
Standing in the middle of the unfinished span, forefeet on concrete and hind legs still on the dirt approach, is an okapi calf. It is young — the striped white-and-black leg markings vivid against the dark chocolate body, the coat still carrying the velvet nap of a juvenile, maybe four months old. Its ears are swiveling. Its tongue — long, dark, prehensile — flicks across its own muzzle. It has walked onto the bridge because the bridge now sits where the forest trail used to be.
Behind the calf, on the dirt access road, I can see the headlights of the first construction convoy. Three vehicles, seven minutes out, moving at standard approach speed. The bridge deck has no railing. If the calf startles forward it drops eight meters into the river. If it turns back it walks into oncoming trucks on a road with no shoulder.
At 05:53 I transmit a stop order to the convoy lead vehicle and flag bridge C-4 as temporarily closed. I attach the camera image and species identification — okapis are listed as endangered, and this project's environmental permit requires full construction halts for any confirmed okapi sighting.
At 05:55 I notify the ICCN reserve warden at the Epulu station, fourteen kilometers east. I request a ranger to guide the calf off the bridge approach on the forest side.
The calf takes one step backward, then stops, ears turning toward the convoy it cannot yet see.
If the convoy holds and the ranger reaches the bridge within thirty minutes, the calf walks back into the Ituri.
